I think it is entirely up to your own tastes. My sister and I (late 20s/early 30s) did not plan on getting it. But then I upgraded my ticket to an AP, so it was automatically included. And we LOVED IT! So many awesome photos, including rides, characters (we aren't even really character people), random shots, and especially Magic Shots. At the end of our trip we made it a mission to get as many Magic Shots as possible! If we had not gotten it, we would have very few photos of both of us together (I know we can ask the PP, but we probably wouldn't have bothered stopping for most of the photographers we did stop for). For example, during our trip we went to Universal and didn't get any photos done. We didn't have any shots of both of us together and I have only one photo of myself the entire day!
So, for my opinion, I'd say, yes, get it. It's a drop in the bucket when you consider the overall expense of the vacation, and helps give you tangible reminders of your trip.
